Application filed August 17, 1922.

To all lwhom z'z'mag/ concern.'

Be it known that I, MATTHEW CRAIG NEILL, of the town of Agassia, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Chairs, of which the following is a specification.

My invention relates to improvements in chairs, and the object of the invention is to devise a chair characterized with a number of self-contained adjustments so that it may be used with equal facility and convenience for household, hospital, or oiiice purposes.

I attain this object by the construction illustrated in the accompanying drawings in whichz- Fig. 1 is a front view, in perspective, of the chair used as an ordinary chair.

Fig. 2 is a back view, in perspective, of Fig. l. y

Fig. 3 is a perspective viev.' of the chair used as a bed or couch. f

Fig. 4 is a perspective view of the bed table chair.

Fig. 5 is a detail view of an alternative arrangement of the leaf shown in Fig. 4.

Fig. 6 is a perspective view of the chair as an arm chair.

Similar gures of reference indicate similar parts throughout the several vievvs.

The chair consists of a seat 1 supported on the front legs 2 and 3 and the back legs 4 and 5, the back legs being extended vertically as at 6 and 7 and braced as at 3 and 9 to form the back for the chair. Under: the seat a drawer 10 is provided and under the seat at a suitable distance therefrom is earried on suitable bars a` removable shelf 11 on Which a folded mattress 12 may be `supported for use as described later. Disposed close to the back of the chair and spaced apart so as to be slightly wider than the same are two parallel side bars 13 and 14 lying normally vertical connected together adjacent their lower endsby a connecting bar 15 While adjacent their upper ends theyare connect-ed by a rod 16 which rod normally rests ina pair of hooks 17 and 18 secured into the back members 6 and 7,a series of these hooks being arranged in vertically spaced pairs, as shown in Figs. 1 and 2. 19 and 20 indicate guide plates secured to the` back members 6 and 7 within which the rod 16 is freely movable during adjustment and which prevent detachment of the rod from ythe chair. 0n the outer face of each Serial No. 582,536.

. guide plate are secured headed Vstuds 21,

these being arranged one above the other and suitably spaced apart, and swingably connected to each bar 13 and 14 respectively are links 22 and 23 provided with eyed ends 24 and 25 adapted to hook over the heads of the studs 21,as hereinafter described, and also over the ends of the rod 16 which project through the side bars, as at 25CL and 25h. 26`27 and 2829 indicate arms pivotally connected at one end as at -31and 32--33 respectively to-bars 13 and 14 and lying normally parallel therewith, which arms are adapted to be swung outwardly and rested onel on the other to form arms for the chair, as shownin Fig. 6, arms 26 and 28 being swung horizontally and arms 27 and 29 vertically, suitable notches 34 and 35 being provided in the arms for locking engagement when in the extended position.

The side bars 13 and 14 are grooved on the inside` as at 36 and slidably mounted in the grooves is a table 37 the side edges ofV which are provided'with notches y38 with any of which a pin 39 which projects through the bar 14 `may be engaged to prevent inadvertent displacement of the table after adjustment and the pin is secured to the leaf j 40 of ahinge 41 secured to the bar so that it maybe swung clear of the notched edge of the table when adjusting tlielsame. 42 in-` dicates a board book rest hinged at one end to the top of the table 37 provided at its hinged end with a ledge 43 While adjacent its opposite end an aperture 44 is provided through which may be extended a strut 45 having notches 46 adapted `to engageuthe edge of the aperture and support theboard in an inclined adjusted position and the strut 45 is hingedly connected at one end, indicated by the numeral 47, to the table 37 and when not in use it is laid into a groove 48 `in the table, being held Ain place byfak laterally swingable clip 49 `pivotally'connected to the table adjacent one kside of the groove and the free end of the strut. 50 indicates a spring tongue adapted to extend through the aperture 44 of the board when the same is folded down and prevent it from inadvertent swinging movement. A supportingstandard 51 is detachably ycarried by the chair for the support of the table, as hereinafter described, and `this standard consists of a tube 52 having a vertical slot 53 and a plurality of notches 54 in its wall arranged one above the other with which co-acts a piny 55 slidable in the slot and secured to a rod 56 slidable in the tube, from which it will be seen that the rod 56 is vertically adjustable in the tube and that it may be held in any vertically adjusted position by the engagement of the pin 55 1n a notch 54 by giving the rod a slight turn when the pin is opposite the notch.

The chair according to the foregoing construction is capable of adjustment to various forms which will now be described.:

ln use as an ordinary chair the several parts are folded and arranged as shown in Figs. 1 and 2, the side bars 13 and 14 being disposed vertically and the table 37 being seated in the grooves 36, the arms 26--27 and 23-29 being'also folded to lie parallel with the side bars. To use as an arm chair with cushioned seat and back the side bars 13 and 14 are swung over the top of the chair so that the connecting bar 15 rests on the front legs 2 and 3, the side bars being then supported in an inclined position, and the arms 26-27 and 23-29 are then arranged t-o form the side arms of the chair, all as shown in Figs. 6, the height of the arms being vertically adjusted by raising or lowering the bar 16 in the hooks 17 and 18. 7 hen arranging the chair in this fashion the table 37 is first of all removed and after arrangement, the mattress 12 is taken from place on the shelf 11, and laid over the seat and against the back of the chair, attaching the loops found on each side of the top end and shown in Figs. 1 and 2 to the extensions on either endjof the rod 16 over which the eyed ends 24 and 25 of the links 22 and 23 are placed so that the loops are thus retained in position. The chair is then ready for use as cushioned arm chair.

When required for use as a bed or couch with mattress, as. shown by the full lines in Fig.' 3 the side arms 26-f27 and 28-29 are maintained in their folded position against the side bars 13 and 14, which are extended to lie horizontally, the bar 16 being dropped to its lowest adjustment and the eyed ends 24 and 25 of links 22 and 23 hooked over the lowermost headed studs 21 so that the rear ends of the side bars are thus supported from the studs. The shelf 11 is then removed from its place under the seat of the chair and after removing the table 37 from the side bar grooves, the shelf is placed in the grooves and slid therein against the chair seat, after which the table 37 is re-inserted in the grooves and slid against the shelf, the book-rest 42 being opened at right angles to the. table and its free end rested on the floor to su port the outer ends, of the side bars 13 anc 14. The mattress 12 is then laidv on frame thus formed, enabling the chair to be used as a bed or couch.

The arrangement just described and shown by 42 in Fig. 3 enables the device to be used as an invalid leg extension chair the only difference in the arrangement being that shelfl 11 is not used as in the bed. The table 37, however, is maintained in the same position So that a space seat and the table and thus when the patient is seated in the chair, the leg rest formed by table 37 may be adjusted at a suitable distance from the seat to accommodate either one leg or two in a horizontal position by sliding the table in or out. The mattress 12 may be placed on the seat and against the back to form a. cushion, the loops being attached over the protruding ends of the chair back.

For a bed-table chair the side bars 13 and 14 are still maintained in a horizont-al position as just described but they are raised to a suitable height, as shown by the dotted line view in Fig. 3, being supported by the links 22 and 23. The table 37 and book rest 42 are folded together and placed in` the grooves of the side bars and slid thereinto as far as is necessary to extend over the bed, the table being held in position by the pin 39. To ensure safety in use the bed-table chair thus formed should be placed with the seat or back against the bed.

The preceding description of a bed-table chair applies equally to the arangement for a. writing or reading bed-table chair with the exception that the table 37 is turned over and inserted in the grooves 36 and the book rest 42 raised as far as may be required to face towards the chair, being supported in its raised position by the strut 45, as shown in Fig. 4, while for a patient in bed the table is turned round before insertingl it in the grooves so that the book rest when raised may face sidewise of the chair, as shown. in Fig. 5. formation just described and shown in Fig. 4, the chair may be used as a dumbwaiter by turning the table right side up andsliding it between the side bars 13 and 14 against the back of the chair, while for a side table as shown by the dotted lines in Fig. 6, the shelf 11 is first of all inserted in the grooves and slid back against the chair, the table 37 being then inserted and slid back against the shelf, the pin 39 then engaging a notch 38 to prevent displacement of the table 37. The outer end of the side table thus formed may be supported and rendered perfectly safe for use by placing the adjustable standard 51 under it, the vertical adjustment of which may be made in the manner hereinbefore described. If so desired, the chair may be used as a writing or reading desk by a person seated in the chair, after placing it in the positions described for the bed-table chair or reading Ior writing bed-table chair, care being taken is provided between the chair Similarly, while in the the dotted line position of the book-rest to drop the adjustable standard to the de sired height.
